http://CollisionBlast.com - - In this video we are going to learn some tips for block sanding when using Motor Guard's new A -- 3 blocking kit.. The new blocking kit by motor guard works well for blocking all types of surfaces. The kit provides different blocks rigid and flexible for the different shapes of contours and surfaces that you will be sanding on. When blocking it's important to cross sand the surface, as it will provide a level surface and help feather edge all filler edges to a smooth transition from filler to the metal. Another thing you want to do when block sanding it to use long blocking strokes. This will prevent a choppy wavy appearance that may be seen after painting the surface. This kit also comes with a new flexible pad that works real well around corners by allowing the block to wrap completely around the corner to properly sand the repair area. If you have not tried this blocking kit I encourage you to give it a try. I think that you will really like the blocks and how it fits the different contours on a vehicle body. Step-By Step Directions Step 1 -- after applying the body filler use 36 grit sandpaper to shape the body filler. This step can be done before the body filler is completely cured to speed up the process. P Step 2 - apply guide coat to the repair area to help identify highs and lows. Step 3 -- block sand the filler using 80 grit sandpaper to remove the 36 great . Remember when sanding body filler or primer to always use cross a sanding technique. This will help level the surface and feather all edges smooth Step 4 - once the 36 great scratches have been removed reapply guide coat and block sand using 150 grit sand paper. Step 5 - now that the scratches that have been blocked out with 150, you are not now ready to properly clean the surface, mask the surface, and apply primer. Step 6 - once the primer has completely dried, block sand the primer using 320 grit sand paper. Be sure to apply guide coat before blocking to help you identify the highs and lows. Step 7 -- once you have block sanded the surface with 320 grit sandpaper and it looks good, final sand the repair area and any area that paint will be applied with 500 grit sand paper. Now you are ready to move on to the painting process. To learn more about Motor Guard products, visit their website at http://MotorGuard.com
